Particle wipe generator

This is a tool for making particle wipes! I wrote the important bits for the heart wipe in Cherry Kisses, and it was a pain in the ass, so I figured I'd share it and save you the trouble of doing geometry.

It's probably faster to try it out and click around, instead of reading an explanation.

Works with Ren'Py's ImageDissolve, RPG Maker's Graphics.transition(), or a simple shader.
